I am thinking about upgrading, but I am not sure I will see enough of a difference to make it worth it. I am not a huge gamer, just love technology and do alot of picture and video editing. right now I run the pentium D 950 with a ati radeon x850 pro video card and 1gb ddr ram. Sometimes I think I should just get another gig of ram and make it ddr2 with a pci express video card. What do ya think. I have a great heat sink so I do not have problems with the cpu overheating. I do understand the c2d runs cooler and you can't compare the mgz between the two. Any advise would be great. Thanks!
